PLATE-HOLDER FOR .PHOTOGRAPHIC CAMERAS.

SPECIFICATION forming part of Letters Patent No. 280,166, dated June 26,1883.

Application filed May 27, '1882.

T all whom, it may concern:

Be it known that l, MA'rHrAs FLAMMANG, of Newark, in the county of EsseXand State of New Jersey, have invented a certain new and usefulImprovement in Plate-Holders for Photographic Cameras, 'of which thefollowing is a speciiication.

My improvement relates .particularly to plate-holders which comprise aframe, a septum, and two doors or covers which may be slid into and outof the'frame, all being so arranged as to adapt the plate-holder toreceive two plates.

The object of my improvement is to provide for fastening the septum, oravv stopper used in conjunction therewith, in place in the frame bymeans of a device which shall not improvement.

project beyondvthe frame, s'o as to interfere with the packing of anumber of plate-holders together, and to suit its being carried in thepocket.

The improvement consists in the combination, with the frame of aplate-holder, a septum, and a stopper used to exclude light, of a devicefor fastening the stopper to the frame, Working within recesses in theframe and stopper, so as not to occupy any space beyond that which isnecessary for the accommodation of the plate-holder, and so as to beprotected against accidental adjustment.

The device mentioned may consist of a hook pivoted within a recess inthe frame and engaging with a pin arranged in a recess in the stopper.

In the accompanying drawings, Figure 1 is a top view of a plate-holderembodying my Fig. 2 is a horizontal section of the same, and Fig. 3 is atransverse section thereof.

Similar letters of reference designate corresponding parts in all theiigures.

`A designates the frame of the plate-holder. lt may be of any suitableform.

B designates a septum iitting in grooves a in the frame A, and adaptedto be slid into and out of the same through one end thereof.

It is provided, as usual with springs b, for pressing against sensitizedplates arranged in grooves c, so as to hold them in position.

fintroduced and withdrawn.

(No model.)

C designates a stopper of ordinary form for closing the end of the framethrough which the septum and the sensitized plates are inserted into andremoved from it.

D designates 'doors or covers fitting in grooves d in the frame, andadapted to be slid into or out of the frame through the end opposite tothat through which the septum B is These doors or covers have affixed tothem hand-pieces E, fitting outside the frame,A and provided withspring-catches F, which are adapted to be engaged with and disengagedfrom staples G, to secure the doors or covers in the' frame.

The stopper C in this example of my invention is permanently fastened tothe septum B.

H designates a device whereby the stopper C is fastened tothe frame tosecure it and the septum B in place. As here shown, such device consistsof a hook pivoted near one end to the top of the frame A in a recess, c,and adapted to engage, at or near the other end, with a pin, J, arrangedin a recess, j', in the stopper C. The recesses e and j' are wide enoughto permit ofthe necessary movements of the hook in engaging with andbeing diseugagedvfrom the pin J From the recess e extend laterally tworecesses, g, which enable the hook to be easily grasped, so that it maybe conveniently manipulated.

As this device for fastening the stopper in place does not projectbeyond the frame or stopper, the plate-holder can be convenientlycarried in the pocket or packed with a number of others, and the deviceis protected against accidental adjustment, so that the stopper cannotbecome unfastened in carrying or handling the plate-holder and admitlight.

Vhat l claim as my invention, and desire to 4secure by Letters Patent,is-

l. The combination, with the frame of a plate-holder, a septum, and astopper used to exclude light, of a device for fastening the stopper tothe frame, and working within recesses in the frame and stopper, so asnot to occupy any space beyond that which is necessary for theaccommodation of the plate-holder, and so as tobe protected againstaccidental adjustment, substantially as specified.
